HOSE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 701,669, dated June 3, 1902.

Application iiled September 5, 190,1.A Serial No. 74,421. (No model.)

T0 all whom, t may concern:

Be it known that I, JAMES EDWIN A'rrm lings, of which the following is a specitica' tion.

My invention relates to improvements in' hose-couplings, and contemplates the provision of a simple, easily-operated, and reliable coupling through the medium of which a hose A4 is a view of amodiiedcupling.

In the said drawings similar letters of reference designate corresponding parts in allv of the views, referring to which- A is a pipe-section. l

B is a hose placed on the lend of the pipesection, and C is my improved coupling. This coupling in the preferred embodiment ofthe invention is formed entirely of metal and..

comprises an open frame a, a cross-bar h,in terposed between and suitably iixed on the side bars of said open frame, a clampingblock d, having apertures eloosely receiving the portions of the side bars of the frame below the cross-bar b and also having its lower side concave, as indicated by f, to snuglyfjit over and conform to the hose, as shown in.' Fig. 2, a lever g, fulcrumed on the cross-bar,

b and having a cam-head h arranged to engage the upper side of the clamping-block d, and spacing-collars g', arranged on the bar between the lever. andV the side bars of' the frame a and adapted to hold the lever against lateral play. The portion of the open frame below the intermediate cross-bar con stitutes a yoke fi, which has for its purpose to receive the hose B after the manner bestv shown in`Fig. 2, while the portionj of said frame above the cross-bar is inclined or pitched slightly toward the right and is de- 'fsigned'to serve asa stop for the lever g when the sameis thrown uplinto the position shown in Fig; l.

Inusing my improved coupling the hose is passed .through the yoke of frame a belowr the clamping-block d and is then slipped on the pipe, faucet, or the like, after which the lever g is thrown up into the position shown in Figs. l and 2. When the lever is thus ad j listed, its cam-head 72 will crowd the block ddown on the hose, and the hose will be securely clamped between the block and the lower end of the yokev and its connection to the pipe or the like rendered perfectly watertight. It will also be observed that when the upper portion of the lever is swung beyond the vertical plane of the bar b and rests against the upper portion j of the frame there is no liability of it casually leaving such position and relieving the pressure on the hose. When, however, it is desired to disconnect the hose from' the pipe or other device on which it is placed, thev same may be readily accomplished by throwing the lever toward the left and then Ldrawing the hose O the pipe.

When desirable, two of my improved coup` lings may be used to connect two sections of hose to a short pipe section orv union interposed between them. l

. The modified coupling shown in Fig. 4 is designed more particularly for use on large hose and comp'risesa yoke t', designed to receive a hose and having the ends of its side 'bars threaded, as indicated by 2, a clampingxyoke, nuts j', mounted on the threaded ends of the yoke, a cross-bar h', disposed below the nuts j and having apertures loosely receiving the side'bars of the yoke, and a lever g', fulcrumed on said cross-bar b and having a cam-head h', arranged to engagethe upper side of the clamping-block d. Vhen'the lever g is thrown in the direction indicated by arrow into a horizontalrpo'sition, its cam-head will crowd the block d" down on a hose arranged Ain the yoke, and thereby securely clamp the hose on the pipe, nipple, or the IOO like arranged therein, while when said lever is swung up into the position shown the hose will be relieved of pressure and may then be readily removed from the pipe or nipple. The Coupling shown in Fig. et is designed,as stated, for use on large hose, and the nutsj" are provided in order that the cross-bar b may be moved nearer the bight of the yoke to compensate for wear of the hose arranged in the yoke.

It will be appreciated from the foregoing that in addition to being simple, efficient, and susceptible of lquick and easy operation my improved coupling is very compact and embodies no parts that are liable to get out of order after a short period of use.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall Within the scope of my claims.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s

1. The hose-coupling described comprising the yoke adapted to receive a hose in its bight, a cross-bar bridging the yoke and bearing a cam-lever, and the clamping-block movable on the side bars of the yoke between the bight thereof and the cam-lever; said clampingblock being separate from the cam-lever, and

arranged to be pressed and held by the same against the hose.

2. In a hose-coupling, the combination of a frame having a yoke at one end and an inclined portion at its opposite end, a clampingblock movable on the side bars of the yoke, and a lever fulcrumed in the frame and having a cam-head for engaging the clampingblock; said lever being adapted when rocked to carry the cam-head into engagement with the clamping-block to bring up against the inclined portion of the frame.

3. The combination of a pipe-section,a hose arranged on and receiving the end of the same, and the coupling described comprising,r the open frame having the yoke at one end receiving the hose, and the inclined portion at its opposite end, the clamping-block movable on the side bars of the yoke and having the concave under side, the cross-bar conne'cting the side bars of the frame above the f TIESSGS.
